The present disclosure relates to a portable vibrating seat in which by a vibrating unit directly fastened to an insert inserted into and formed integrally with a cushion member disposed in a main body unit, vibration is strongly transmitted to a spectator, thereby improving an interest of the spectator.

BACKGROUND ART

Movie theaters may be widely classified into a general movie theater which shows a general movie (two-dimensional image), a special movie theater at a place for providing amusement, such as a theme park, and an exhibition movie theater for education or for providing public relations at a museum/public relation center/exhibition hall.

In general, a person mainly sees three-dimensional images, but because a person sees two-dimensional images when viewing the images, which are captured using image capturing devices such as a camera or a camcorder, through a screen in a general movie theater, and as a result, a stereoscopic effect is greatly degraded.

A movie screening facility in the related art such as a general movie theater simply provides movies to spectators, but recently, due to propagation of digital media capable of performing bidirectional signal communication and development of movie industries, new types of movies are provided, and various effects are provided to the spectator in addition to movie screening. That is, the general movie theater in the related art is a place which simply allows people to see the movies in visual and auditory manners, but recently, the movie theater becomes a place that allows people to see the movie in a visual manner, and allows people to directly feel various effects.

In general, the movie theater where people may feel stereoscopic effects of the movies in a visual manner while seeing the movies, which are specially made, is generally called a ‘3D movie theater’, and other than the 3D movie theater, a movie theater, which allows people to feel five sensory senses such as tactile sense, olfactory sense, and the like, in addition to visual and auditory senses when seeing the movies, is referred to as a ‘4D movie theater’.

Recently, in the 3D movie theater, the 4D movie theater, or the theme movie theater, in order to provide spectators with vibration corresponding to situations in the movie, vibrating units are installed in chairs in the movie theater, and the chairs are controlled to be automatically vibrated by allowing the vibrating unit to be operated in conjunction with heavy low tone sound of the movie, thereby allowing the spectators to more strongly feel the vibration.

Hereinafter, a vibrating chair in the related art will be described in more detail.
